摘要:
The present invention is concerned with the preparation of chemical intermediates, namely, beta-amino-acrylic acid ester derivatives of nitrogen heterocycles, i.e. pyridine, quinoline, quinoxaline, pyrazine, pyrimidine and the like. Said intermediates are cyclized to form pyrido-pyrimidine type final products possessing analgesic activity.
